During the discharge process of industrial and commercial energy storage systems, due to power fluctuations, changes in load power consumption and other reasons, reverse flow of electrical energy may also occur. The anti-backflow solution can effectively avoid this problem and ensure the safe and efficient operation of the energy storage system.
As the scale of global industrial and commercial electricity consumption continues to expand, industrial and commercial energy storage technology has attracted more and more attention. The backflow problem in energy storage systems has always been a problem that troubles users.
After installing a photovoltaic system with anti-backflow, the power generated by the photovoltaic is only supplied to the local load, and the power generated by the photovoltaic energy storage system can be controlled not to be sent to the grid.
Preventing the occurrence of backflow problems is called backflow prevention. In order to prevent backflow problems, anti-backflow devices came into being.
Electricity can be stored directly for a short time in capacitors, somewhat longer electrochemically in, and much longer chemically (e.g. hydrogen), mechanically (e.g. pumped hydropower) or as heat. The first pumped hydroelectricity was constructed at the end of the 19th century around in Italy, Austria, and Switzerland. The technique rapidly expanded during the 196.
